Aldosterone ELISA kits are assays designed to detect the steroid hormone aldosterone, which is produced by the adrenal cortex. It acts on the distal tubules and collecting ducts of the kidneys and plays a key role in the maintenance of water and electrolyte balance in the body, by controlling water and sodium retention as well as potassium excretion. The primary mineralocorticoid in humans, it aids in homeostasis through the regulation of blood pressure and plasma ion levels. Altered levels of aldosterone can contribute to cardiovascular and kidney diseases. Visit the supplier page for more information about detection range and reactivity.
